Abstract
Método para la preparación de una máquina de rectificar (10), controlada por ordenador, para rectificar una pieza compuesta alargada (18) que tiene regiones cilíndricas concéntricas (31), con una compensación de la excentricidad inducida por el proceso, en por lo menos una de las citadas regiones cilíndricas, en el que dicha región cilíndrica se rectifica cilíndricamente hasta obtener su forma final, caracterizado por las etapas de medir (50) toda excentricidad no deseada inducida por el proceso de rectificado, así como la(s) posición(es) angular(es) de la misma en dicha región concéntrica, y ajustar las instrucciones del programa o las señales de control del avance de la muela almacenadas en el ordenador (32) que controla la máquina de rectificar, de modo que, durante el rectificado ulterior de la pieza, se controle el avance de la muela para rectificar una forma excéntrica, igual y opuesta, a la medida, compensando de este modo la excentricidad inducida por el proceso.Method for the preparation of a computer-controlled grinding machine (10) for grinding an elongated composite part (18) having concentric cylindrical regions (31), with compensation of the process-induced eccentricity, in at least one of said cylindrical regions, wherein said cylindrical region is cylindrically rectified until its final shape is obtained, characterized by the steps of measuring (50) any unwanted eccentricity induced by the grinding process, as well as the position (s) ( es) angular (s) thereof in said concentric region, and adjust the program instructions or the wheel advance control signals stored in the computer (32) that the grinding machine controls, so that, during the subsequent grinding of the piece, the wheel advance is controlled to rectify an eccentric shape, equal and opposite, to the extent, compensating in this way the eccentricity induced by the process or.
